Mission Details

Comet Interceptor

The Comet Interceptor is a robotic spacecraft mission led by the European Space Agency (ESA) planned for a 2028 launch. The spacecraft will be "parked" at the Sun-Earth L2 point and wait for up to three years for a long-period comet to flyby at a reachable distance. The Principal Investigator is Geraint Jones, from the Mullard Space Science Laboratory at the United Kingdom. The maximum cost of the spacecraft is set at €150M, excluding science instruments and launch services.
